Already replaced the diff bushes with after-market poly ..... am putting the car on the hoist this afternoon for the engineer's stethoscope treatment. Be interesting to see what I find.

I have noticed that backlash in the diff is "growing" so I may have a pinion bearing issue and/or pinion/ring gear wear.

I post the results when known this evening.
